The oxidant-antioxidant balance disorders underlie a number of acute and chronic diseases of the central nervous system (CNS). It is believed that oxidative stress plays a role in the pathogenesis of migraine. The study objective was to assess the processes of lipid peroxidation with malondialdehyde (MDA) as its major indicator and to determine the(More)
A prospective study was undertaken of 129 children with spastic cerebral palsy to clarify the relationship between magnetic resonance imaging (MRI) findings and clinical features of cerebral palsy. Low birth weight, asphyxia, prematurity, seizures, mental development, Gross Motor Function Classification System, and MRI findings were analyzed. Significant(More)
Epilepsy is rarely considered as a major component of Down syndrome. We evaluated the prevalence of epileptic seizures in 252 (97 girls and 155 boys) children and adolescents with Down syndrome evaluated at Department of Pediatric Neurology between 1994 and 2007. Results showed that 15 (6%) patients had epileptic seizures: 8 partial seizures; 1 infantile(More)
The aim of this study was to evaluate the influence of antiepileptic therapy on antioxidant enzyme activity and lipid peroxidation in the erythrocytes of children with epilepsy. For this purpose, the activity of superoxide dismutase, glutathione peroxidase, and glutathione reductase and the malondialdehyde concentration in 61 healthy children and 90(More)
PURPOSE Down syndrome (DS), or trisomia 21, is one of the most common autosomal mutations, with mental impairment as the constant symptom. Proton magnetic resonance spectroscopy (1HMRS) allows evaluation of this metabolism in DS children. The study objective was the morphological evaluation of the brain in magnetic resonance imaging (MRI) and assessment of(More)
PURPOSE The aim was to compare quantitative EEG analysis of REM sleep in children with Down syndrome (DS) and normal age-matched controls. MATERIAL AND METHODS Twenty-one channel EEG of 21 patients with Down syndrome and 21 normal children, with ages ranging from 1 to 8 years, were submitted to quantitative analysis EEG of discharge-free epochs. The(More)
BACKGROUND AND PURPOSE Down syndrome (DS) is the most common genetic cause of mental retardation with deficits in language and memory. Mental retardation of varying degrees is the most consistent feature of DS. The objective of this study was to use high-resolution magnetic resonance imaging (MRI) techniques to investigate the volumes of the hippocampus,(More)
Studies have shown fluctuations of cytokine levels in patients with migraine headaches; however, further studies are needed to verify these results. Our previous studies suggest increased levels of pro-inflammatory cytokines, such as IL-1alpha, sTNF-RI and TNF-alpha, in children with migraine headaches. In this study, we analyzed anti-inflammatory cytokines(More)
Down syndrome (DS), or trisomy 21, is one of the most common autosomal mutations. The overexpression of the β-amyloid precursor protein gene, located on chromosome 21, causes an increased production of the specific amyloid. The current study is a continuation of our earlier investigations relating to the profile of metabolic changes in the frontal lobes of(More)
Many experimental studies indicate that some antiepileptic drugs possess neuroprotective properties in varied models of neuronal injury. Levetiracetam is a second-generation antiepileptic drug with a novel mechanism of action. In the present study, we evaluated the putative neuroprotective effect of levetiracetam on primary hippocampal cultures at seven day(More)
